Your ninja built a custom Minecraft mod this week. Here's how to open and play it at home in five steps:
Download your ninja's mod pack. Your ninja's Sensei uploaded each week's finished mods to Google Drive on Friday afternoon. Pick the week your ninja attended:
Download MCreator. MCreator is the same modding software your ninja used at camp — it's what opens the mod pack. Go to mcreator.net/download and pick MCreator 2026.1 for your computer:
Windows: EXE installer
Mac: DMG image (Intel or Apple silicon)
Linux: TAR archive
Install MCreator. Run the installer you just downloaded and follow the prompts. Open MCreator once installation finishes.
Import the mod pack. In MCreator, click "Import from file," select the mod pack you downloaded in Step 1, then choose a folder for the new project. MCreator will take a few minutes to set things up — once it finishes, every element your ninja built this week will be open in the editor, ready to explore.
Play the mod in MCreator. Inside MCreator, click the "Run Client" button at the top of the workspace. MCreator launches Minecraft with the mod loaded — your ninja can play through everything they built, show off their favorites, and even let you try them yourself.
What We Covered This Week
Each session's work stacked on the last — one ever-growing mod pack. Ninjas used MCreator (the same tool real Minecraft modders use) plus Blockbench for 3D mob design. Click any topic to expand.
Custom Ore & Custom Weapon
Got oriented in MCreator — mod elements, the texture editor, saving, navigating the workspace
Created a custom ore — painted the texture, named it (one ninja called theirs "Code Ninjium"), and set properties like hardness, harvest level, and world-generation rules
Wrote a smelting recipe to turn the ore into a custom ingot via the furnace
Designed a custom weapon (sword, axe, or trident) and balanced damage, durability, attack speed, and enchantability against real Minecraft reference values
Built the weapon's crafting recipe and tested it with an elbow partner
Procedures, Custom TNT & Custom Potion
Learned procedures and event triggers — "WHEN this happens, THAT happens" — the same pattern real game code uses
Built a custom TNT block with two-texture top/bottom design and coded the explosion procedure (if/do/else, Is block powered, Play sound, Remove block, Explode at)
Tested TNT by blowing up the houses they built that morning — "5… 4… 3… 2… 1… EXPLODE!"
Voted as a class to build either an Instant Explode Potion or an Arrow Rain Potion — then created the potion effect, icon, item, and brewing recipe (Awkward Potion + custom ingredient)
Coded the potion's procedure to fire on the "effect applied" event
Custom Enchantment & Full Armor Set
Built a mob arena to stress-test the mods — then voted between a Lightning Sword Enchant or a Shield Deflect Enchant (with blockedamount * 2 math)
Coded the enchantment with event triggers, if-do logic, particle effects, and sound — applied via /enchant Dev modName:enchantmentName
Designed a full custom armor set — helmet, chestplate, leggings, and boots — with two textures each (inventory icon + on-body armor texture) and durability balanced against real Minecraft values
Programmed armor procedures using the per-tick event (20 times per second while worn): boots = fly, leggings = speed, helmet and chestplate = ninja's choice
Battled in the mob arena with full gear, swapped builds with elbow partners, and debugged with the Sensei
Custom Biome, Blocks, Trees & Plant
Explored what makes Minecraft's existing biomes distinct — resources, mobs, terrain, trees — and tested knowledge with a Kahoot biomes quiz
Created custom biome blocks (surface, log, leaves, planks) and tagged leaves so they wouldn't decay off the custom logs
Built a custom biome with its own water/grass/foliage colors, tree generation rules, structure spawns (villages, igloos, mansions), and entity spawning (passive cows and chickens, hostile creepers and skeletons with weighted spawn rates)
Designed a custom plant (sapling, flower, or grass-style) that spawns in the biome, then teleported in to test using /locate biome modname:biomename
Custom Mob (3D Modeled) & Mod Pack Export
Started with a Survival mode warm-up — faced a harder dimension using every modded tool from the week (custom sword, armor, potions, biome)
Met Blockbench — a real 3D modeling tool used by the Minecraft modding community — and picked a base model (human, chicken, creeper, witch, ghast, and more)
Designed the mob's 3D texture using Blockbench's paintbrush, color picker, fill, eraser, draw shape, and gradient tools — then exported as a Minecraft skin
Imported into MCreator and built the full entity — custom spawn egg colors, optional boss health bar, sounds (living/hurt/death), AI behavior (hostile mob or passive creature), HP, damage, knockback, immunities, speed, follow range, rideability, and spawn rules (including in their own custom biome from Day 4)
Exported the mod as a working .jar file — ready to install on home Minecraft with Forge
